Step-by-step explanation:
The periodicity of function is 
<em><u>Solution:</u></em>
Given that we have to find the period of function
<em><u>Given function is:</u></em>

<em><u>Use the below formula:</u></em>

Thus,

Now find the periodicity of cos(x)
We know that,
periodicity of cos(x) = 
Therefore,

Thus the periodicity of function is
